RJ-485 RJ-232 to wireless or PC without cable

Is there way I can read data at set frequency e.g. 868.25 or 915MHz without 3rd party device (using just PC?)

Background:
I want to "talk" with the inverters in my loft used by solar panels, without 3rd party device.

I have a Aurora Photovolatic Inverter which have a device PVI RadioModule attached. This is transmitting data at 868.25MHz or 915MHz. It is connected to a RJ-232 RJ-485 in inverter box.
I have 3rd party device PVI-DESKTOP-IT that can currently task with PVI RadioModule. I would like to talk to PVI RadioModule direct from PC though.  The device is a bit clunky. Because inverter is in loft I can't directly cable to the RJ-323 RJ-435

No, the rs4850 and the items are proprietary.and would use awareness to receive the data and using a USB you can connect to the TS 4850.

RJ-485 not 4850

RJ means Registered Jack. RS is a Recommended Standard.

RS485 is a standard for multidrop communications links: https://en.wikipedia.org/wiki/RS-485

Your adapter uses a RJ45 connector.

To directly communicate with your device you would need to connect to it directly with a cable or use a WiFi adapter. Both would require proprietary software to talk to the device.
